Evaluation of autologous plasma skin test in patients with chronic idiopathic urticaria.

Background: The pathophysiological mechanism of chronic urticaria is still poorly understood and its aetiology is considered to have an autoreactive basis. Autologous serum skin tests (ASSTs) and autologous plasma skin tests (APSTs) comprise the simplest ways for diagnosing autoreactive urticaria (with autoantibodies, histamine-releasing factor and coagulation factors, especially thrombin) in a clinical setting. However, there are still some questions about the specificity of these tests.

Antistreptococcal treatment of guttate psoriasis: a controlled study.

Background: The role of streptococcal infection in the initiation of guttate psoriasis is well-recognized. But the treatment results with oral erythromycin and phenoxymethylpenicillin are conflicting.

Objective: Our purpose was to evaluate the effectiveness of these antibiotics in the treatment of streptococcus associated guttate psoriasis comparing with a control group.

Inflammation and hypercoagulable state in adult psoriatic men.

Hyperhomocysteinaemia is a well-known risk factor for cardiovascular disease and plays a role in atherothrombosis. Psoriasis is a common chronic and recurrent inflammatory skin disease associated with increased thrombosis. The aim of this study was to examine serum homocysteine levels and their relationships with inflammatory and atherothrombotic markers in psoriasis.

Dermatitis herpetiformis and vitiligo.

Dermatitis herpetiformis (DH) is a rare immunobullous disorder of the skin that is associated with gluten hypersensitivity. Subepidermal IgA-type antibody deposition against tissue transglutaminase leads to dense neutrophilic microabscess and eventually into vesicles in dermal papillae, which may occasionally merge into bullae. Being a subepidermal vesiculobullous disorder, DH is frequently associated with postinflammatory pigmentary changes, particularly hypopigmentation.

Eosinophilic cellulitis presented with semicircular pattern.

Eosinophilic cellulitis (Wells' syndrome) is a rare condition of unknown etiology and pathogenesis. It is characterized by erythematous plaques and a histological picture of dermal eosinophilic infiltration with "flame figures". The typical clinical presentation of eosinophilic cellulitis is mildly pruritic cellulite-like plaques.

Evaluation of patients with symptomatic dermographism.

Background: Dermographism or 'simple' dermographism, which has been noted in about 1.5% to 5% of healthy individuals, is regarded as a normal physiological phenomenon. However, in symptomatic dermographism (SD), even light pressure or rubbing from clothes may provoke widespread weal-and-flare reactions with itching and burning.

A case of coumarin necrosis with penile and pedal involvement.

A 57-year-old male patient with advanced adenocarcinoma of the lung, who was administered oral anticoagulant therapy because of pulmonary embolism, developed coumarin necrosis confined to the penis and feet. To our knowledge, this patient showing acral involvement is the seventh case of coumarin-induced penile necrosis reported to date.

Intradermal antigen tests and the Koebner phenomenon in psoriasis.

Background: Psoriasis is one of several dermatologic conditions in which nonspecific irritation may elicit the disease where it was not previously present. In this study we aimed to assess the cutaneous cellular immune reaction with intradermal antigen tests and the relation between Koebner's phenomenon and intradermal antigens.

Methods: Thirty psoriasis patients and 20 control subjects were tested with 0.

Acquired unilateral nevoid telangiectasia syndrome.

We describe a man with acquired unilateral nevoid telangiectasia syndrome, in whom no underlying disease, alcohol abuse or physiological conditions causing hormonal changes are demonstrable. To our knowledge, this is the first case of acquired unilateral nevoid telangiectasia syndrome seen in a healthy adult male and not associated with a hyperestrogenaemic state and estrogen receptor abnormality. This case report casts doubt on the commonly held view that unilateral nevoid telangiectasia syndrome is an estrogen-sensitive nevoid anomaly.

Efficacy and safety of oral fluconazole in the treatment of patients with tinea corporis, cruris or pedis or cutaneous candidosis : a multicentre, open, noncomparative study.

The efficacy, safety, required duration of treatment, and patient preference for oral fluconazole 150 mg/week in the treatment of 521 patients with cutaneous candidosis, tinea corporis, tinea cruris or tinea pedis were assessed in an open, multicentre, noncomparative trial. Patients received weekly doses of fluconazole 150mg for an average of 4.65 weeks.
